International AccountEdge Pro and Network Edition v12 have been tested on the new Mac OS X 10.9 (Mavericks) operating system and are compatible. International AccountEdge Pro and Network Edition v12 are now our official 10.9 supported versions. International AccountEdge products older than v12 will not be officially supported or updated for 10.9.

Apple has removed Sync Services support, which AccountEdge used to sync with Apple’s Contacts app (aka Address Book). As a result, Address Book sync is no longer supported in AccountEdge with Mac OS X 10.9. (In AccountEdge Pro, the Sync button is displayed when running on Mac OS X 10.6 through 10.9, but when you attempt to sync on a Mavericks OS, you’ll get the message: The synchronization session was not created.)

If you are planning to upgrade to 10.9, we suggest you upgrade to the latest version of AccountEdge and, of course, back up your company files.
